Are the 1.9L rocker studs the screw-in or press-in variety? What's the best valve guide to run? Any good ideas on a valve retainer replacement?
Agreed, aluminum is for racing only, and they should be changed annually. I remember sucking a valve through an aluminum retainer on my old Corolla 2TC, it was pretty ugly @ 8200 rpms....David McCollam said:Hey there,
I've got the Crower retainers, the machinist at the shop says that aluminum retainers in any form are no good. The folks at Isky said they use them on import applications all the time. Who's to say.
I talked to RD Spring in Hesperia, CA and they made some 9mm retainers for Opels in the past. I'm trying to get them to make some for the stock valve stem dimensions.
